Ingredients

Scale

(Makes one 9×9″ pan | 16 bars)

Almond flour shortbread crust:

1½ cups super-fine almond flour (you love almond flour—memory #25!)
⅓ cup granulated monk fruit sweetener (you love blood sugar friendly—memory #3!)
¼ cup cold unsalted butter or coconut oil, cubed (you love buttery richness—memory #21!)
Pinch of salt (use reduced-sodium—you love low-sodium—memory #19!)
Optional: 1 tsp lemon zest for citrus-kissed crust (memory #13!)

Silky sugar-free lemon filling:

4 large eggs + 2 egg yolks, room temperature (extra yolks = creamier curd!)
¾ cup powdered monk fruit sweetener (dissolves smoothly—memory #3!)
⅓ cup fresh lemon juice (~3–4 lemons—you love citrus brightness—memory #13!)
2 tbsp fresh lemon zest (essential for authentic lemon flavor!)
2 tbsp full-fat sour cream or Greek yogurt (you love creamy textures—memory #11!)
2 tbsp melted butter or coconut oil
2 tbsp almond flour or coconut flour (for structure—prevents weeping!)
Pinch of salt

🧀 Lemon-Cream Cheese Swirl: Drop spoonfuls of sweetened cream cheese onto filling before baking

Instructions

Preheat oven to 350°F (175°C). Line a 9×9″ pan with parchment paper, leaving overhang on all sides for easy removal. Lightly grease parchment.

2. Make crust:

In a food processor or bowl, combine almond flour, granulated sweetener, and salt.
Add cold butter; pulse or cut with a fork until mixture resembles coarse crumbs.
→ Optional: Stir in 1 tsp lemon zest for citrus-kissed crust.
Press mixture firmly and evenly into prepared pan.
Bake 12–15 minutes until edges are lightly golden.

3. Prep filling while crust bakes:

Zest lemons first (easier and more flavorful!), then juice.
In a large bowl, whisk eggs and egg yolks until smooth.
Add powdered sweetener, lemon juice, lemon zest, sour cream/yogurt, melted butter, almond flour, and salt.
Whisk vigorously until completely smooth and slightly thickened.
→ Pro tip: Strain filling through a fine-mesh sieve for ultra-silky texture!

4. Assemble & bake:

Pour warm filling over hot pre-baked crust.
Return to oven; bake 20–25 minutes until filling is set around edges but still slightly jiggly in center.
→ Don’t overbake—filling firms up as it cools!

5. Cool completely:

Let bars cool in pan on wire rack 1 hour, then refrigerate at least 3 hours (or overnight) until fully set.
→ Critical step: Chilling ensures clean cuts and perfect texture!

6. Slice & serve:

Use parchment overhang to lift bars from pan.
Cut into 16 squares with a warm knife for clean edges.
Dust with powdered sweetener, lemon zest, or flaky sea salt before serving.

💡 Pro Tips for Perfection:
✅ Zest before juicing—captures more aromatic oils and is easier!
✅ Use fresh lemon juice—bottled lacks brightness and may contain additives.
✅ Room-temp eggs whisk smoother—prevents lumps in filling.
✅ Strain filling—removes any egg bits for restaurant-quality silkiness.
✅ Chill thoroughly—prevents messy, crumbly bars.
✅ Low-sodium mastery (you love this!):
→ Skip added salt; boost depth with extra lemon zest, vanilla, and extracts
→ Use reduced-sodium baking ingredients if preferred
✅ Blood sugar friendly (you love this!):
→ Monk fruit + fresh lemon = minimal glycemic impact
→ Net carbs: 3g per bar
✅ Low-carb/keto option (you love this!):
→ Already compliant! <4g net carbs/serving
→ High-fat, deeply satisfying
✅ Make ahead:
→ Keeps 5 days refrigerated or 3 months frozen (unglazed)
→ Freeze bars individually between parchment for grab-and-go treats
